DEFINITION

Classification: 248/526

(under subclass 525) Support wherein the exertion of a downward force by the staff (i.e., resulting either from its weight or from an externally-applied force) causes the supporting legs to grip the staff more tightly.

(1) Note. While the structure of this subclass usually do not appear to differ materially from those of the preceding subclass (525) and therefore might function similarly, nevertheless the patents which appear in this subclass (526) are those which claim or otherwise disclose the functional relationship described.
